Locate the main control compartment under the dashboard near the driver’s side footwell to quickly identify the primary terminals. Confirm each connector’s position using the stamped numbers on the metal rails to avoid misrouting circuits.
Inspect each slot carefully before inserting any connectors as several circuits carry high current and can trigger short circuits if placed incorrectly. Use a test meter to verify active pathways and continuity before energizing the system.
Separate the auxiliary lines in the engine bay by following color-coded insulation codes and clip positions. This prevents cross-contact with ignition circuits and lighting feeds, which can cause sporadic malfunctions.
Document each connection with labels or photos before disassembly. This method ensures precise reassembly and reduces troubleshooting time during maintenance or upgrades.
Prioritize grounding points near the firewall and chassis for stable performance of all electrical components. Check that each ground strap is free from corrosion and fully tightened to maintain consistent voltage levels.
Electrical Panel Reference and Slot Guide for Compact City Cars

Access the interior control panel beneath the driver’s side dashboard to quickly identify the primary slots. Each slot is numbered, and labels indicate the circuits for lighting, ignition, and auxiliary components.
Check the color-coded terminals before connecting any lines to prevent misrouting. Red connectors generally carry battery power, while black or brown ones lead to ground points. Using a test meter ensures correct circuit identification.
Main Slot Assignments

Slots 1 through 6 handle high-current devices such as headlights, horn, and starter relay. Avoid inserting low-amp connectors into these positions to prevent overheating and potential damage.
Slots 7 to 12 are reserved for auxiliary circuits including infotainment, cabin lighting, and accessory ports. Verify each connection against the stamped reference numbers on the panel to maintain system integrity.
Auxiliary Slot Organization
Group low-current lines together and route them along the panel edge. Keep connectors snug and use retaining clips where possible to prevent vibration-induced disconnections during motion.
Document the configuration with photos or notes before any maintenance. Proper labeling accelerates troubleshooting and ensures rapid restoration of the original configuration after upgrades or repairs.
Locating Interior Power Panel and Terminal Positions
Access the control module under the dashboard on the driver’s side to identify all major terminals. Remove the cover panel carefully to reveal numbered connectors and labeled ports for each circuit. Ensure the ignition is off to prevent short circuits.
Main Terminal Locations
Primary terminals are grouped near the central hinge of the panel and supply energy to essential components such as headlights, starter relay, and horn. Use a small flashlight to read the printed numbers on the terminals and verify their functions with a multimeter.
Auxiliary Terminal Positions
- Auxiliary circuits are arranged along the perimeter of the panel, including cabin lighting, dashboard indicators, and entertainment systems.
- Color-coded wires indicate positive and negative paths; red or orange leads carry voltage while black or brown leads connect to ground points.
- Maintain a clear path between terminals to prevent accidental contact or shorting when connecting additional devices.
